Ohh, Nolan blew every last bit of realism capital with that microwave generator that was somehow powerful enough to instantly vaporize all the water in the city's sewers and yet had no effect on the water in human bodies, induced no electric currents or discharges in the city's metal, etc. Not to mention, why bother engineering the fear toxin into a waterborne form and then vaporize all the water? Why not just make it a gas in the first place?
Considering the genre hes using, Nolan has found a very good realism level combined with the comic book aspect.
After watching this, Robin Williams would make a good Hugo Strange IMO...
